  • Need some clarification...
When I purchased this unit, I was excited as it described the total BTU which will help in my projects of melting Coper and Glass. At first, I attached both burners to one tank but once I fired up the 2nd burner both did not have enough to keep full burn. This required that I purchased another tank and connect each to different tanks. Here I found that one of the controls was faulty so purchased another and all was good. On one of my runs both burners running at full suddenly started to burn back to the value. I turned the gas down to control and it was good from there on. To totally convert the Copper and Glass to the right temperature for working it took about 45 to 60 minutes. Now, with all these challenges I contacted the manufacturer whereby they recommend I should run at maximum for up to 30 minutes not to over burn the system. To accomplish I will be utilizing my smaller furnace to pre-heat then transfer to this furnace to finish the temperature. This newer furnace is great just has a few limitations that can be addressed to be successful. ... show more

  • Stopped working
This worked great for melting aluminum. About 700 degrees Celsius. As soon as i turned it to 1100 degrees celsius to melt down some copper it heated all the way , and then just turned off after 10 mins never turned back on. I returned it
